Well, I think that one is pretty clear:

    2.5
    Copies

    [...] For clarity, You may copy only the entire package or piece of
    the Apple Software and Services in its entirety and only for use as
    permitted herein. You may not alter the Apple Software or Services
    in any way in such copy, e.g., You are expressly prohibited from
    separately using the Apple SDKs or attempting to run any part of the
    Apple Software on non-Apple-branded hardware.  [...]

So the current Xcode SDK very clearly is off-limits for use within GUB.
It's probably either some Darwin SDK or we'll stop providing MacOSX
packagers/versions altogether.
